ok here are reason why halo 4s campain was good maybe the best
1 it showed charcter dervolpement something ive barley seen in a halo game
2 it was emotinal near the end so that means good writing and it was good writing
3 said befor but once agin showed chief human side
4 had a good varity of leavels
5 a good chiff hanger ending maybe anwered in sparten ops yes it did rember halo 2s lol so much hate about the edning
6 many more reason but at this time all i can think off
also here are reason brutes and engineers are not in halo 4 the storm covies found requim and the storm has no brutes in it so u see also no eginners becase they fled explained in halo novel glasslands
